Abstract (en)

[origin: WO0169302A2] The disclosed scanning structure includes an apparatus for light delivery and light receiving from a light-excitable area on a substrate to be measured by the scanning structure. The light delivery and receiving apparatus may include an optical fiber having a proximal end and a distal end which transmits light having a certain wavelength or light with several varying wavelengths to excite the substrate samples. This optical fiber may also simultaneously receive light which may be emitted by fluorescing samples on the substrate. The scanning structure also may further include a holder for the optical fiber that is able to transverse variable distances over the substrate to be measured or examined. Holders may include galvano scanners as well as resonating suspension beams. A light source, e.g., a laser, may be optically coupled to the optic fiber's proximal end. And this light source may be of a certain wavelength, but multiple light sources each having a different wavelength may also be used simultaneously by coupling the light sources into either a single optic fiber through wavelength multiplexers or by placing individual optic fibers carrying differing wavelengths in close proximity to each other. As the light is transmitted down to the substrate through the optic fiber, the fiber is sufficiently close to the substrate microarray so that it can also receive the emitted fluorescing light.
